PSU choice , please help

thermaltake over CM anyday IMO is that psu you are looking at the trw-1000x?

i think it's called thermaltake toughpower 1025w or so , the cooler master one is the silentpro M

but do u know if the current PSU is good enough to handle the gtx 590 ? cuz if so that could save me quite some money

most people here (including me) prefer the brands of antec, corsair, seasonic, xfx, pc power and cooling, enermax, and silverstone. while brands like coolermaster, ocz, and thermaltake will also do the job we often don't put them into the same class as above.

as far as your current PSU, it should power the GTX 590, it has enough power and amps on its 12v rail, plus you already own it. the reviews for it are OK, basically stating its nothing special but capable.

I really dont know anything about the gtx 590, i know that a 750watt good psu like a corsair pro can handle 2 gtx 580s in sli.

well i heard some awful replies about the fsp- everest powersupplies , so i was wondering if any of those are true ... some people also recommended that i replace it immediately so thats why im thinking of swapping it to a better one .

the FSP Everest 700w was killed on jonnyguru

If you're planning on swapping anyway I'd definitely go with ct1615's brand recommendations. I go with Corsair myself and have never had a single problem with any of the PSU's I've gotten from them. Your 800w would be enough power but if I were you I'd jump up to a 1000w+ to leave a buffer for later upgrades like more hard drives, blu-ray, and any peripherals that may draw power through USB ports.

There are two 1000 Watt models in the Thermaltake Toughpower Series:
Model W0155RU - Now discontinued but there may still be available stock in the distribution channel. Non-Modular. 80Plus.
Model W0132 - Replaces the W0155RU. Hybrid Modular. 80Plus Bronze.
Both models have CWT (Channel Well Technology) as the OEM.

The Cooler Master Silent Pro M1000 (RS-A00-AMBA-J3) is an 80Plus Bronze hybrid modular unit made by FSP (Fortron/Source Product) Group.

A reference version GeForce GTX 590 has a Maximum Graphics Card Power of 365 Watts (i.e. will draw up to a maximum of 30.4 Amps from the +12 Volt rails).

The FSP Everest 80Plus 800W Power Supply Unit is labeled as being able to provide a Maximum Combined +12V Power of 775 Watts (64.6 Amps).

If the power supply isn't defective it shouldn't have any problems powering your system with a GeForce GTX 590.
