cpu core i5 6400
and a 1tb wd drive and i am planning to put another 1-2 drives

Change your PSU to a better quality model with enough watts to power your rig and has ample PCIE connectors.

The GTX 770 is a 230W card (Nvidia even recommends a 600W PSU, though a good-quality 500W-550W will suffice) and would require 1x 6-pin and 1x 8-pin PCIE connectors to power it. Unfortunately, your low-quality PSU does...

Yes sir you can run without any problem but if there is not enough connector for your graphics card in PSU you gotta buy and contact it with 4X peripheral .

your PSU is enough for 32 Gb ram + i7 + GeForce GTX 1080 and you have lower graphics then what i have said. go on give it a shot :) works prefect.

thanks

Going by the weak 25a 12v rail that is actually a 300w psu not 500w, so not its not going to power a 770. Even attempting to use it to power a 770 would put the entire computer(and possibly your house) at risk of damage. When it comes to power supplys segotep is a heaping pile of fail.

yo wtf i don't removedunderstand removed by telling me about the amp and volts and other stuff... that's why i am here..
all i want to know is wheather i can put the gpu without problems and can run it without problems...
1 of the 4pin is in the mobo and 1 is away..
the 6 pin conector i used to run the r7 370 that i got back then
and my question is if the gtx 770 uses 1 6pin conector? because as far as i know the psu will run my system...(i was told that the i5 doesen't require as much power and also nvidia) so i must be fine?

The Segotep ATX-500WH only has 1x 6-pin PCIE connector. The "2x 4pin" connectors you mentioned is not for the PCIE / GPU, but rather, for the CPU's ATX12V power (connected to the motherboard).

Furthermore, the specs of such low-quality PSU indicate only a max of 204W at the +12V rail (but marketed as a "500W" PSU):

This means that your 230W GPU will already exceed the PSU's rated +12V power leaving you with insufficient juice to power the rest of your components.

I would highly recommend for you to get any of these PSUs to replace your current one:

For tight-budget (best value):

Corsair CX550M (550W)
45.8A (550W) at +12V | 2x 6+2pin PCIE connectors | 40C rated oper. temp. | Semi-Modular | 5-year warranty
Corsair - CXM 550W 80+ Bronze Certified Semi-Modular ATX Power Supply ($36.99 @ Newegg)

Seasonic M12II-520 EVO (520W)
40A (480W) at +12V | 2x 6+2pin PCIE connectors | 40C rated oper. temp. | Fully-Modular | 5-year warranty
SeaSonic - 520W 80+ Bronze Certified Fully-Modular ATX Power Supply ($35.89 @ Newegg)

Much better quality units (but more expensive):

Seasonic G-550 (550W)
45A (540W) at +12V | 2x 6+2pin PCIE connectors | 50C rated oper. temp. | Semi-Modular | 5-year warranty
SeaSonic - G 550W 80+ Gold Certified Semi-Modular ATX Power Supply ($68.99 @ SuperBiiz)

Corsair RM550x (550W) <--- Personal choice
45.8A (550W) at +12V | 2x 6+2pin PCIE connectors | 50C rated oper. temp. | Fully-Modular | 10-year warranty
Corsair - RMx 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($74.98 @ Newegg)

EVGA SuperNova G2 550 (550W)
45.8A (550W) at +12V | 1x 6-pin + 2x 6+2pin PCIE connectors | 50C rated oper. temp. | Fully-Modular | 7-year warranty
EVGA - SuperNOVA G2 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($85.88 @ OutletPC)

Ofc yes
a gtx 770 uses about 250w
Then there is ram...
hard drives
and other misc powered items.
so it will be close to 450w
i would say yes it will work 100 percent fine there is not danger and no damage.

A good 500w unit would likely be fine, but the 500w unit the op has is far from good.
A good 500w psu can deliver most to all of its 500w rating on the 12v rail. If you knew anything about how a psu works in modern system you'd know the 12v is the most important rail as it is the most used. The OPs unit only has 300w on the 12v rail.

A stock gtx 770 can use 200w by itself which leaves a meager 100w for the cpu and other components that required power from the 12v rail. Plus given the low quality nature of the psu loading it up close to or past it's rating is ill advised as they tend to blow and when psus like this pop they have a good chance of damaging other parts.

well the gpu uses a 6 pin conector and/or a 2x8 pin?
if in the case i can power with the 6pin conector or is the 2x8 pin required along the 6 pin? i will try my luck i think...the psu is under warranty and i have about 6 months more...
if the psu held the r7 370 and the i5 it must hold the gtx 700?
and if it doesen't hold it and explodes or stoped working it will cause problem to the other components?

Best case scenario the system shuts down under load.
Bad case it pops and frys anything or everything it powers.
Worst case it explodes, causing a fire that burns down your house.

My advice is to not even try it mathmatically it's not going to have enough power.

GPU = 1x 6-pin AND 1x 8-pin connectors at 230W

Your PSU only has 1x 6-pin connector. As said, you can't use the 2x4pin as that is NOT for the GPU (only for the CPU/MB).

Also, as said, your PSU only provides 25A at +12V (i.e., 300W) but is rated only as "+12V 204W(MAX)".

Get a better PSU with ample 6-pin and 6+2pin connectors, with ample wattage/amps, and a better quality for reliability, efficiency, and SAFETY.
