and for this I bought THERMALTAKE W0423RE litepower 450w black edition
It has main 1 24 pin main power connector,one 4+4 pin PCU power connector ,one 6pin PCI-E connector ,three 4pin pheripheral cpnnector , 4 pin floppy connector , 5 pin S-ATA connector...

is this enough for running my pc smoothly..

again I am planning to buy e normal sata 1tb... will I face any problem
thanx in advance

No, that Power Supply will be insufficient. AMD recommends at least 30 amps (500 watt+) combined on the +12 volt rails. That PSU has a 13 amp and 14 amp rail and its only 450 watts. You will want at least a 550 watt to power that GPU.

If you are looking to get a new power supply, I would get this PSU as the minimum (Corsair CX500)

If you have the cash, look at a higher wattage PSU (600 watt+) or a gold-rated PSU

Build Quality Summary




Overall the build quality if the Litepower 450W is certainly not awe inspiring in any way, it simply looks like another basic FSP Epsilon based unit. The exterior of the unit screams beige box basic, and the design is sparse, inexpesive, and getting a bit long in the tooth. The component selection is acceptable for an entry level unit and you certainly won't mistake it for a high end unit with things like all Teapo capacitors, unsleeved wiring, and a group regulated topology. The one odd build point when compared to other FSP power supplies (or really most any OEM we have seen), is the use of 3 bridge rectifiers here for some reason. However, if this approach works we can’t knock it too much. Let’s move now and see if the performance of the unit matches the run of the mill build quality.


I don't get there thinking on this part of there review----- '''for a high end unit with things like all Teapo capacitors,''' more like 2ed tire to me

I don't think that is related to his situation.

That PSU is not enough. It has no rating for one, which is risky when you are close to maxing a unit. That GPU will use a large amount of power and that isn't a low end cpu. You can look up each of the maximum power consumption's of each of these components and I would recommend a 600w psu to be safe, but more never hurts if you can afford it.

The R9-270 is a sub-150W GPU and the i4-4570 uses around 50W unless you also use the IGP, which is unlikely with a R9-270 in there. Throw in 50W more for the rest of the build, you get about 250W peak.

A good quality 450-500W PSU would be more than sufficient.
