After I upgraded my system,(added a second hard drive, second optical drive, 8800gts512, tv card) in every game imaginable It would eventually freeze or crash within 30mins. Now to support my system I only have a 430w Thermaltek psu. So my system goes like this: Motherboard & Cpu
Two optical drives
Two Hard Drives
8800gts512
x-fi extreme gamer
Tv tuner
Is my 430w enough to support this system, If it actually is:headexplode: What else could be causing these crashes?

List of games:
Call of Duty 4
Crysis
World in Conflict
Even in CS:source

Id say no its not. Really tho it is its just a junky unstable PSU at high loads. If it was a better psu then ea it would be

430w on a single rail PSU? Hell no, that's weak sauce. Upgrade to about...650w, that gives you enough power to OC and possibly SLi.

I have 550w and it works well for my 8800gts and pentium 4 extreme. I'd suggest you get at least 500 watts. I'm getting 850w sooon yay :>

I have 550w also, it's got 2 rails, so more stability. Don't get PSUs that have an odd number for the rails, like that Antec Trio or whatever. Just stick with 2 or 4, but more over, stick with 4 rails.

ok sum 1 plz tell me .... what is a rail?

Not entierly true 1 rail is always better then 2 and way better then 3 ect. and so on. They started using multi rails for safety and heat dissipation. huge 12V rail runs very hot and can fluctuate. There harder to make and more expensive at times to manufacture. most are now switching back to 1 large rail for SLI support

rail is a term used to define a feed of power from your PSU. You can have 1 large 12V rail (powers your GPU's hard rives ect.) or you can have 2,3, 4 smaller ones. The problem is if you have multiple 12V power sources they will be weaker the 1 larger rail and can be overloaded if you hook it up wrong or over load 1 rail.

ahhh i see!

So it's just like a partitioning of the wattage.

there may be one 100w strand that you could overload with 5hdds or something... correct me if im wrong

correct. A PSU's wattage is determined by all of its rails combined. The 12V is the most important. It is safer to have 1 Large 12V rail then a bunch of weak ass worthless ones. For instance you can have a single 40Arail or 4 10's. I can easily overload the 10A rail so I would have to balance the load between the rails or else i can trip the PSU or burn out a rail.

How the hell can you manage that? Most quad-railed PSUs have high wattage. It's alot better to have multiple rails because there can be a dedicated rail to the GPU and Mobo and the rest can be for drives and other peripherals. Single rails can become too shaky when you put too much stress on it.

I used to overload my 700W silverstone all the time. I used 1 rail for my GPU and another for the rest of the PC I just daisy chained every thing. Instant trip :p My 750W silencer with its 60A single rail doesn't have that problem (nana2)

I have 2 20A rails and I have absolutely no problem. Complete stability. Most 8800 series cards need 24A to keep it running. I have a rated 40A to give. 1 for the GPU, and some from the other rail. The other rail has enough to power every thing else.

I used to have a coolermaster extreme 430Watt, when i got my 8800GT games like crysis and COD4 started crashing. When i resetted my CPU clocks back to stock it worked fine. Now upgraded to 510 watt PSU and also have my CPU overclocked, everything seems fine now.

Its probably your PSU.

i use a Antec 480W single rail 28a 12v and it runs my 8800GT and CPU both heavily overclocked no problem. but anything less i bet i would have stability issues.

personally if i didnt already have that PS i would have went a little bigger :) 550-600 maybe. anything under 750-800W are really cheap now.

Seems to be a consensus that I do indeed need a new psu. From what I have read, I think I'm gonna go with a single 12v+ rail, 650w-750w, and im not sure if I want to go with modular cable support. Anyone have any recommendations?

This pc power and cooling seems like a great deal with the $80 instant savings, only $170 raight now, but not in stock...

NOOO!!

Go with either this or this:

Depending on your case's cooling. I went with the dual 80mm fans because of my case.

These are much cheaper and more wattage. (I don't know about the quality of the single 135mm fan one but I ordered the dual 80mm fans because I've red every single review and there are only a few people who said they had problems.

I had 2 of those 430 Thermaltakes die on me. You will prolly be saving yourself some time by getting a new one anyways. I went with an Antec 500 watt and have had no problems since. My vote is for antec.

My thermaltek has served me well, coming up on two years now, but it's definitely time to move on...

Those Rosewills are running on 4 12v+ rails, I think I trying to stick with the single 12v+ rail, unless someone convinces me otherwise.

PC Power is a good brand so you should be alright and since nobody has suggested you may want to check the link below to see what you really need, I usually go with the worst case 100%, 100%, 50% for the capacitors aging when doing my calculations just to leave a margin for error.

It said I need 614w, so I don't want to go any lower than 700w, 750 would be preferable. So 750w, single 12v+ rail, I think those are my requirements. I dont want to skimp on my psu, so I'm going for quality.

Seems reasonable to me a good quality power supply is always the place to start when putting together a system you may even want to go 800-850w just for an extra margin.

Those crashes are a pretty clear indication that 430w is not enough for your current system.

Thermaltake is already fine - I'd take one of the Tough Power series which has an 80%+ efficiency:
This one with 700w will leave a nice margin for future upgrades:

If you intend on running sli w/ your 8800gts512, I'd recommend a stronger psu like this 850w one which has plenty of ressources for sli:

There are also versions of these psus w/ cable management (i.e. modular cables), which is very nice for an uncluttered case, but I don't see them at newegg.
