AMD A64X2 4200+ (5% OC with no additional volts) + Freezer 64 Pro
DFI LANParty UT nF4 Ultra-D
3GB RAM (4 Sticks)
640GB HDD + 250GB HDD
Lots of USB peripherals (Joystick, wheel etc... All 8 USB ports are occupied)
and an Enermax Liberty 400W which holds everything very well.
I want to upgraded my system with:
Core i5 750
Asus based P55 Mobo
8GB DDR3 1333 (4 Sticks)
Will the Liberty 400W be able to run this system or I'll have to buy a new PSU?
It was considered as a very good PSU at the time I bought it, it delivers very high amps, do you still think I'd need a new PSU? I'm very low on budget and I don't want to waste money on a new PSU that I don't need.
It does look like the Enermax Liberty 400 watt power supply will be able to handle your upgrade.
Here are the official ATI Radeon™ HD 4870 System Requirements:
PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
500 watt or greater power supply with two 75 watt, 6-pin, PCI Express® power connectors.
600 Watt or greater power supply with four 75 watt, 6-pin, PCI Express® power connectors for ATI CrossFireX™ technology in dual mode.
The recommendations are for an entire system.
Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. An example would be the Antec Earthwatts series which is a major improvement over Antec’s older psu’s like the Basiq models.
