PSU QUESTION!!

[LM-Tech]

SO im running a regular desktop mobo,
NZXT Mid CASE with some minor LED Lights on the front.
Core i7 920 CPU
ATI RADEON HD 4850
4gb's DDR3
1TB HD
6 - 120mm fans
DVD/CD drive
and a All-In-One memory Card Reader

But im running a 450Watt Corsair power supply, i was wondering if thats not enough for my system.. im also upgrading my CPU cooler to either a Thermalright TRUE or a Ultra Chilltec.

please some comments and suggestion, thanks in advance!

I say you'd need a 550 or 650 W just to be safe.

What can possibly happen when running low on watts?

What can possibly happen when running low on watts?

Not all of your components will get enough power and some of them might not even start up. As iFargle suggested, get a 550W or 650W power supply. I know that for my brothers computer a 450W just barely works, and his specs are about 1/2 yours.

 

[LM-Tech]

what would you suggest?

i need 5 molex, 2 satas, a 24pin power, a 8pin and a 6 pin. and a decent price lol
i recently bought my current PSU.

Newegg.com - Thermaltake EVO_Blue W0306RU 550W ATX 12V 2.3 / EPS 12V 2.91 SLI Ready CrossFire Certified Modular Active PFC Power Supply - Power Supplies

$99.99 USD

Says nothing about how many Molex, but it has the 6 pin, 8 pin, 20+4 pin power, and 4 SATA connections

Your system is fine on the 450.. Its not just watts, also Amps, and the corsair is fine for thsat.

When/if you upgrade your gpu to a bigger card, then think about a new psu... YOU"LL actually need one, but till then, don't worry.

As an example of corsair.. ran 2x260's 2 hds, 4 fans and an oc q6600 with a heat sink, on a 520hx.

Thats good to hear, i was also reading that corsair is good for this kind of thing..

im also making a CPU cooler upgrade to the Chilltech comes with a controller you think that would be any problem patonb? thanks.

That I'm not sure of.

Youre starting to get up on the psu limit. But not over yet, I just don't know how much the Chilltec draws.

i couldn't find the exact specs but does this help?

Thermoelectric Chip: 40 x 40 / 12V DC

Total Power Dissipation:
- 0% Load = 5 W
- 50% Load = 28 W
- 100% Load = 50 W
