5770 on 420w real power

[badc0re]

I have conf q6600,3gb ddr2, 1hdd and dvd-rw. I tried this config on 550w with real power 370w and it wont work(for games - computer freezes). I want to buy SP-ATX-420WTN-PFC and does it worth buying this PS.

The Power Supply Requirement for your whole system is:
450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX technology in dual mode)

Therefore I recommend you to go for one of the following ones (if you are not thinking about doing CF):

I'll probably buy GlacialPower GP-PS550BP coz of my budget.

Maybe you shoud read this article before take a final decision: http://www.hardwaresecrets.com/article/479/8

I would like to make you know how important is to have a quality power supply. It can become a nightmare, trust me.

If you tell me what your budget is, I could look for something cheaper than my other recommendations but with enough quality.

well my budget is around 40$, but that's not that much of a problem. The real problem is the offers in the stores. I mean :

p.s i am not in Uk or USA

GlacialTech 550w is it good for the config i have or it is a cheap garbage so doesn't worth paying it ?

 

[Henry Chinaski]

The problem is not the wattage, but the very low quality of this power supply.

As you have said, you don't have much to choose. Anyway, If I were you I would go for the CM Silent Pro 500W RS500-AMBAD3-EU (87,56€).

I know it's much more expensive than your budget but, in my opinion, it's worth.

Here you have a qualified review (german):
